This front end 21 is formed no enlargements 26 formed withthe sidewalls of the pointed front end 21 and located inwardly otthe castingb. These enlargements 26 are provided with burner openings 27 which are provided for uniformly heatingthe front end of the iron with respect to the remaining portion ot'the same, The, tubular burner elements 28 are illustrated as having their front ends received within the pocketed portions 26 of the, cored enlargements 26 and are arranged with theirburner openings 29 presented to the fianie pockets 10 in the bottomcasting5. In Figs. 10, .11 and12 the rear end wall 20 of this castin'gb is illustrated as being formed with the tubular bosses 30 which. receive the, rear ends of the burner tubes 28 which are closed. by the removable caps 31 held in place by thesc'rews- 32..In Fig. 9, the top edges ofthe side walls 20'a're illustrated as being provided with thenotches 33 for perinitting the entrance ofair into the interior of the body casting 6L Byreterring to Figs. 5 and 9, it will beseen that the cored enlargements 26 are providedwithvertically extending passageways 34 which are open at their upper ends .35-and communicate with the said cored enlargements 26,attheirlowerends.

The operation of this sad-iron for converting industrial or denatured alcohol into gas suitable to be burnt for heating the iron is as follows 7 It will be seen that the tank 37 may be filled to a desired level with industrial or denatured alcohol by removing the cap 38. After this tank 37 has been provided with alcohol, the latter will feed by gravity through the tube 40 into the converter trap coupling 41. This coupling will fill up with liquid alcohol until it reaches the level of theconverter tubes 42 whereupon it will fiow through these tubes, it being noted by inspecting Fig. 1 that the converter tubes 42 are inclined downwardly toward the front end of the sad-iron. The alcohol in passing through these converter tubes is caused to travel a tortuous path by the filler elements 52 and 53 located in these converter tubes. These filler elements are intended to produce a whirlin motion by the spiral wires 52 and twisted strands 53. The flow of the alcohol into the burner tubes 28 and cored enlargements 26 is controlled by the valve stems which may be rotated by means of the valve wheels 50 carried by the projecting ends of these stems 50.

To start the heating of the iron, the valve stems 50 should be operated for permitting a small quantity of the alcohol in its liquid state to be fed into the flame pockets 10 formed in the bottom casting 5. then be shut off for preventing further feeding of the liquid fuel into the bottom casting and the liquid fuel that has been discharged 7 should then be lighted. The burning of this liquid fuel causes the converter tubes 42 and the burner tubes 29 to be heated. The heating of the converter tubes 42 and the liquid fuel therein, will cause this fuel to vaporize or in other words, the liquid fllBlzVVlll first start to'boil and will then be changed into highly expanded gas or vapor. As this gas isproduced, the valve stems 50 may be operated for withdrawing their tapered ends from the valve seats 49 for permitting this gas to pass through the passageways 48, in the valve blocks 43, and into the passageways 51. This gas passes downwardly through these pas-' sageways 51 and enters the tubular passageways 34 formed in the body casting 6. The travel of the gases through these passageways The valves should the tank 37 to the burners and this retarding of the travel of the fuel will permit the same to be converted into gas by the time it arrives at the valve blocks 43. The filler elements 52 and 53 and the converter trap c011 pling 41 will prevent the return of any of the gas into the tank 37.

It is now believed that the construction and operation of this sad-iron will be understood from-the above detail description and that no further explanation is believed necessary.

It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the inventionor the scope of the subjoined claims. 7
